Whether a scratched pan is safe to use depends entirely on the material it is made of.
A scratched non-stick pan is not ideal for safe cooking, as the coating's integrity has been compromised, making it more likely to release small particles or chemicals when cooking.
When a nonstick pan made with PFAS is scratched or chipped, small particles can flake off into the food you are making. A 2022 study found that scratched pans coated with these chemicals release thousands to millions of microplastics and nanoplastics.
Patches and scratches are perfectly okay on your iron pans
This concern would be warranted if you were cooking on a synthetic-coated non-stick pan. However, uneven patches and scratches are very normal (and actually expected) for naturally seasoned wrought iron! They are designed to be lifelong workhorses, after all.
“If the nonstick pan has any chips or scratches, it should be thrown away,” says Breann Chai, who leads cookware testing at Consumer Reports. “The nonstick coating could be flaking off into any food being cooked in the pan, and you would want to avoid ingesting particles from the nonstick coating,” she says.
Non-stick pans may be an ideal choice in home kitchens, but in professional commercial kitchens, their safety, heat resistance, service life and cooking effect limitations make them unpopular with chefs.
Signs It Is Time to Replace Your Nonstick Pans
Visual signs of nonstick pan deterioration include chips, scratches, and uneven coloring. Metal utensils, high heat, and improper cleaning methods significantly damage the nonstick surface. Chemical breakdown and mechanical stress gradually deteriorate nonstick coatings.
Yes, scratched stainless steel is completely safe to use. Unlike non-stick pans (which can release toxic chemicals when scratched), stainless steel is unreactive and solid throughout. Minor scratches are purely cosmetic and do not release harmful toxins into your food.
Perhaps one of the most effective ways to remove scratches from a car's paint job, a magic eraser is a favorite choice for many. It might not be the best tool in the box for fixing deeper cuts, but it works well on light surface scratches.
If the scratches are fresh, you may end up with flakes of the coating in your food, which we can all agree is not delicious. It can also impact how effective your pan's nonstick abilities are. Scratches, high heat, and general wear and tear will wear down the slick coating on the surface of your pan.
The healthiest pans to cook with are made from cast iron, carbon steel, stainless steel, or pure ceramic. These materials are free from toxic synthetic coatings (like PFAS and Teflon) and will not leach harmful chemicals or microplastics into your food when heated.
Symptoms of Teflon flu or polymer fume fever include chills, fever, fatigue, headache, body aches, and occasional chest tightness and airway irritation. People with underlying lung diseases such as asthma are more likely to develop respiratory symptoms.
You should throw away a nonstick pan when the coating flakes, peels, or becomes deeply scratched, or if it is over 5 years old. Additionally, if the pan has warped, developed rust, or food persistently sticks even after oiling, it is time to replace it.
New research shows that one five-centimeter scratch on a Teflon-coated pan can release over 9,000 microplastics in a single cooking session. If the coating is broken, you're looking at 2.3 million micro and nanoplastics seasoning your dinner. These aren't just plastic bits; they are forever chemicals called PFAS.
Yes, scratched ceramic pans are generally safe to use because their coatings are derived from natural minerals (like sand), making them free of toxic chemicals like PFAS, PFOA, lead, and cadmium. While scratches will ruin the pan's nonstick performance, they do not pose the same severe health hazards as scratched Teflon.
Over time, stainless steel pans can stain and show discoloration. While it doesn't always affect the pan's integrity, be sure to watch for discoloration due to rust. Rust in your food can cause health issues, so it's best to replace of your pans when they start rusting.
No, scratched stainless steel is not considered toxic. Unlike non-stick pans with synthetic coatings, stainless steel does not leach harmful chemicals or microplastics when damaged.
Method with Olive Oil. Dab a clean towel with a small amount of olive oil. Gently buff the stainless steel surface in the direction of the grain. Wipe away any remaining oil with a clean cloth.
Avoid traditional non-stick pans with worn coatings or synthetic "forever chemicals" (PFAS), as well as unlined copper and reactive aluminum. Scratched or overheated pans release toxic fumes or leach heavy metals into your food.
If your non-stick pan is scratched, it is generally safest to replace it, especially if the coating is peeling, flaking, or if the scratches are deep enough to expose the underlying metal.
Non-stick pans (like Teflon) are often considered problematic because their non-stick coatings are made using PFAS, or "forever chemicals". When overheated, these pans can release toxic fumes. When scratched, they can leach microplastics into your food. They also have a shorter lifespan compared to other cookware.
A single scratch on a nonstick surface can release millions of toxic particles, including microplastics and harmful chemicals known as PFAS (per- and polyfluoroalkyl substances), directly into your food.
Non-stick pans should generally be replaced every 3 to 5 years. While high-quality pans with proper care might last up to 7 years, most pans show significant signs of wear within 2 to 3 years. If the coating is peeling, severely scratched, or food consistently sticks, it is time for a new pan.
The healthiest frying pans are made from unreactive, chemical-free materials that do not leach toxins into your food. The best options are cast iron, carbon steel, stainless steel, and pure ceramic. These materials avoid the PFAS, PFOA, and PTFE found in traditional non-stick coatings.
